WebbSCRs are triggered on by a pulse applied through the primary of T1. The SCR string turns on if the positive applied pulse to the gate is of sufficient amplitude to trigger the SCR on. At SCR turn-on, capacitor C discharges through the low impedance On-state of the SCR string. This action induces a negative-going current pulse to the load RL.
